The app is now available as a free download in the App Store, and it's currently only available for iPhone and iPod Touch owners. Facebook Camera is set up very similarly to Instagram and includes most of the same features (including photo filters), but Dirk Stoop, Facebook's product manager for photos, said Facebook was working on this application long before the Instagram acquisition on April 9."
